IMPROVEMENT IN GATES.

TO ALL WHOM IT MAY CONCERN Be it known that I, L. M. Scornonn, of Findley, in the county of Hancock, and State of Ohio, have invented a new' and useful Improvement in Gates; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and'use the same, reference being had to-the accompanying drawings, forming a part ofthis specification.

This invention relates to an improvement in gates, and belongs to that class of double-slide gates, in which the extension gate slides in the main gate. It consists, first, in a double post, the main gate sliding through another pest formed of two upright pieces setinto a grooved slot in the double post. The main gate is provided with rollers, which run between cleats nailed to an underground sill. The extension gate slides on rollers journalled in the upright bars of themain' gate. The horizontal bars of the extension gate look into mortises in the end .post when the gate is closed. The gate may be raised oil the ground by means of the horizontal bars of the extension gate, and by a hand-lever pivoted to the double post and locked at any desired height. In the accompanying drawings 7 v Figure lisa side view partly in section of my improved gate.

Figure 2 is a top view thereof; and

Figure 3 is an end view of the double post.

Similar letters of reference indicate corresponding parts.

A A is-the underground sill, which, in a gate of, say, twelve feet between the posts B and E, should have .a section of six inches square, and extend no less than eight feet on each'side of the double post B. O C are two uprights, bolted or held together so as to form a slotted post, through which the main gate slides horizontally, as presently mentioned. 'The post 0 C slides vertically in the grooved slot in the double post B, carrying the gate with it. The main gate, intended to be two-thirds the clear between the posts B and E, is composed of vertical and horizontal bars D d, the former being placed in pairs, one pair at each end of the main gate, and receiving the horizontal bars between them. The upper and lowermost of the horizontal bars are thicker than the intermediate horizontal bars, and are tenoned at each extremity, so as to be received between the vertical. bars as in a mortise. The uppermost horizontal bar slides on a roller, 0, journalled in the uprights C- C. Rollers D are journalled in the vertical bars D below the lowest horizontal bar, on which rollers the gate is rolled back and forth between the cleats a a, nailed to the underground sill A. The extension gate is also composed of horizontal and vertical bars G H H, in like manner to the main gate, but with the addition of an upright bar, F, on one side only, at about two-thirds of its length from the end H, to prevent the extension gate from being drawn out too far in the main gate. The double uprightsin the main gate and in the extension gate may, if desired, be replaced by a single upright, mortised to receive the horizontal bars. The length of the extension gate should be about one-half of the clear,."whereof no more than two-thirds can be drawn out of the main gate by reason of the upright bar F. The-horizontal'bars of the extension gate slide between the end uprights of the main gate, or through mortises therein if the double uprights be replaced by single uprights. A

friction-roller, g, is journalled in the end uprights of the main gate, and another friction-roller, g, in the ver tical bar H of the extension gate, keeping the horizontal bars Gr oil the horizontal bars d, and-enabling the I ext'ension gate to slide easily in the main gate. One or more of the horizontal bars G extends'beyond the end upright H into a mortise in the post E, as shown by the dotted lines at G, one of them being furnished with a, notch, with which it catches in the post, and locks the gate.- There are several mortises in the post E, at differ ent heights, to receive the prolongation G of the horizontal bars and keep the gate closed, as well when they gate is raised oil the ground as when itis down. The hand-lever pivoted to. the side of the double post B i used to raise the gate, the short arm being insertcd'beneath a horizontal bar, and'raising the main andextension gates and the double post 0 to the desired height, when the gate may be locked by the prolongation of the horizontal bars of the extension gate being inserted in the mortises in the end post E. The double post B, for

a gate of twelve feet in the clear, should be six inches by eighteen inches, with six inches cut out in theiniddle, forming a slot six inches wide, with walls six inches square, provided with lips of about one inch to form the groove.

The above device furnishes a gate at once handy and substantial, and which cannot readily be clog ed either by snow or mud, from which it is readily lifted. There is little or no sag in any part, as the gate nowhere roses 2 rests upon the posts except when locked in a raised position to clear the snow or mud when the horizontalbars of the extension gate rest in the mortises in the end gate E, but when on the ground, its normal position, the main gate rests wholly on the sill. The extension gate can be readily opened and closed again by a man on horseback, while the whole gate can be muchmore readily opened than any swinging gate, nor is any prop required to hold it open while passing through. The'double post B, made as described, will last for many years.

I claim as new, and desire to secure by Letters Patent I 1. The donblepost B, constructed as and for the purposes substantially as above set forth and described.

2. The upright movable post G, working in a groove in the post 13, and provided with the roller 0, substantially as above set forth and described:

3. The main and extension gates, consisting of vertical and horizontal bars I) Ll, F, G, H and H, or their respective equivalents, and provided with rollers D D, g g, in manner and for the purposes substantially as above set forth and described;
